We have 6 pairs of 9800-80 on HA, and we noticed that on all pairs there is a process (SAMsgThread) that runs every 15 minutes that affects the 9800 controller CPU. That process SAMsgThread is the responsible for Smart Licensing operations. Depending on the time of the day the CPU hits 100% and it may affect client transactions depending on the qty of APs that are hosted in the controller.
The controller version now is running 17.6.4 and couple weeks back was on 17.6.2.
I have a ticket opened but they are not helping much. Has anybody experienced this issue?
Looking at the the command "show license eventlog" it displays the following every 15 min:
